write a c++ program that prompts user's first name and last name
Sure! Here is a step-by-step guide to writing a C++ program that prompts the user for their first name and last name:
Step 1: Include the necessary libraries
```
#include <iostream>
#include <string>
```
Step 2: Declare the main function
```
int main() {
// Your code goes here
return 0;
}
```
Step 3: Declare two string variables to store the first name and last name
```
std::string firstName;
std::string lastName;
```
Step 4: Prompt the user to enter their first name and last name
```
std::cout << "Enter your first name: ";
std::cin >> firstName;
std::cout << "Enter your last name: ";
std::cin >> lastName;
```
Step 5: Display the entered first name and last name
```
std::cout << "Your first name is: " << firstName << std::endl;
std::cout << "Your last name is: " << lastName << std::endl;
```
Step 6: End the main function
```
return 0;
```
The complete program should look like this:
```cpp
#include <iostream>
#include <string>
int main() {
std::string firstName;
std::string lastName;
std::cout << "Enter your first name: ";
std::cin >> firstName;
std::cout << "Enter your last name: ";
std::cin >> lastName;
std::cout << "Your first name is: " << firstName << std::endl;
std::cout << "Your last name is: " << lastName << std::endl;
return 0;
}
```
When you run this program, it will prompt you to enter your first name and last name, and then it will display them back to you.
Certainly! Here's a C++ program that prompts the user for their first name and last name:
```cpp
#include <iostream>
#include <string>
int main() {
std::string firstName, lastName;
// Prompt the user for their first name
std::cout << "Enter your first name: ";
std::getline(std::cin, firstName);
// Prompt the user for their last name
std::cout << "Enter your last name: ";
std::getline(std::cin, lastName);
// Display the user's full name
std::cout << "Your full name is: " << firstName << " " << lastName << std::endl;
return 0;
}
```
To get the user's first name and last name, we use the `std::getline` function from the `<string>` library. This function allows us to read an entire line of input, including spaces, from the user. We store the first name in the `firstName` variable and the last name in the `lastName` variable.
Finally, we display the user's full name by concatenating the `firstName` and `lastName` variables using the `<<` operator, and include a space between them.
